“…Apart from the manoeuvring strategy to avoid ice, ships and other platforms operating in cold regions can be protected by the many de-icing and anti-icing methods that reduce ice accretion. Most of these technologies have evolved from the aviation, electric and transportation industries and, among them, those adaptable to the marine environment have been identified for use (Ryerson 2011). Ship sections can also be prioritised in different categories and anti-/de-iced with respect to their implication for the safety standards.…”

“…The application of these chemicals is based on their suitability for the specific area, while also taking into account their disadvantages. For instance, sodium chloride has corrosive properties and tends to be ineffective at lower temperatures, and some of these chemicals absorb the moisture and leave behind the residue, which is slippery and can be hazardous in terms of walking (Ryerson 2011;Shi et al 2013).…”

The aim of this work is to review the phenomenon of icing in marine operations. The focus is on two main sources of icing, namely atmospheric and sea spray. The literature reveals that sea spray icing is the main contributor to marine icing. This work discusses the available ice accretion prediction models on ships and offshore structures. It also reviews the anti-/de-icing technologies that can be implemented on ships operating in cold climate regions. The significance of ice detection is acknowledged, and a brief review of various ice detection technologies is provided. ARTICLE HISTORY

“…Asymmetric or unbalanced accreted ice on, for instance, guyed masts (ISO, 2001) can unbalance the forces and thus threatens their stability or increases the fatigue failure possibility. Loads imposed by ice on equipment and shelter ceilings may cause damage and malfunction (Ryerson, 2008;Ryerson, 2011). Ice sticks easily to surface imperfections such as joints and welds.…”

“…Falling ice and compacted snow during thawing, as well as slippery stairways and deck can cause personnel injuries and potentially increase human error rates (ISO, 2001;Ryerson, 2008). Heavy accretion of ice and accumulation of snow on doors, stairways, pathways, helicopter pad, and life rafts can considerably impair the escape and evacuation efforts in case of emergencies (Crowley, 1988;Ryerson, 2011). Accreted ice or accumulated snow on fire-fighting equipment, ventilations, and manual emergency shutdown systems imposes serious safety and health hazards by reducing the reliability of passive safety barriers.…”

Oil and gas (O&G) industry is expanding its activities into Arctic offshore, where is characterised with severe operating conditions and less-developed infrastructure. Such conditions affect the reliability, availability, and maintainability (RAM) of offshore O&G plants, operations, and activities through different scenarios. Plant RAM analysis provides key information for decision-making on, for instance, life-cycle cost management, inventory management, future investments, establishing maintenance policies, and safety-barrier management. Such decisions are of crucial value in Arctic offshore applications due to higher initial and operational costs. Therefore, a thorough evaluation and quantification of the effects of operating conditions on plant RAM performance play a significant role in such decisionmaking processes. In this regard, the aim of this paper is to broadly review and discuss different elements of offshore operating conditions specific to the Barents Sea, and further investigate various effects of such conditions on plant RAM. The present study can provide fundamental information to the academic and industrial sectors involved in the research and development of Arctic offshore O&G facilities and operations.

Ice and wet-snow accretion on outdoor structures, including power transmission and distribution equipment, is a serious problem for regions experiencing icing conditions.Various de-icing and anti-icing techniques have been developed to date to counter this problem. Most of the techniques currently in use, however, including active de-icing methods, are employed only where accumulations are substantial. Passive approaches to the problem such as anti-icing or icephobic coatings which inhibit or retard ice accumulation on the surfaces are gaining in popularity.Metal corrosion should also be taken into account since metal or metallic alloys are subject to corrosion problems when placed in a humid or aggressive environment; the development of any ice-releasing coatings on Al structures, as they must be durable enough, is thus closely related to anti-corrosive protection of that specific metal.Consequently, this research has made an attempt to prepare coatings, either one layer or multi-layer, for use on polished AA6061 and AA2024 substrates combining the qualities of reduced ice adhesion and improved corrosion resistance. These two alloys are among the most widely used aluminium alloys in transportation systems (including aircraft), electric power industry, military, etc. Both the stability of the coatings in a humid environment and their overall ice-repellent performance was systematically studied.This research work has made a systematic approach to investigating the influence of surface roughness on the ice-releasing potential and the hydrophobic properties of the prepared coating surfaces. All coatings displayed a gradual loss of their hydrophobic properties after ~ 1000 h of immersion in water, and while corrosion of surfaces was also observed, except in the case of surfaces treated with permanganate conversion coatings which provided satisfactory anti-corrosive protection. IllAll flat coated surfaces demonstrated shear stress of ice detachment values which were at least ~ 1.5 times lower than uncoated mirror-polished Al surfaces and about ~ 2 times lower than those observed on as-received Al surfaces. The adhesion reduction factor (ARF) values decreased after as many as 12 icing/de-icing events, implying a certain amount of decay of the coatings.All rough superhydrophobic samples allowed for ice adhesion shear stress values of at least ~ 4 to 7 times lower than those obtained on the uncoated as-received Al surfaces. After 24 icing/de-icing experiments, however, ice adhesion strength increased significantly on those surfaces by a factor of ~ 2 after 24 icing/de-icing cycles.In addition, all flat and rough-coated surfaces gradually lost their hydrophobic properties after nearly each icing/de-icing cycle. Thus, the ice-releasing ability of all samples tested was found to be time-dependent.The work thus reveals that it is possible to prepare coatings which provide the reduced adhesion of ice to Al surfaces, while at the same time also providing some degree of anticorrosive protection.
